SPECIFICATION forming part of Letters Patent No. 672,716, dated April2,3, 1901.

` Application filed September 25, 1900. Serial No. 31,070. (No model.)

To all whom, it may concern:

Be it known that I, HARRY SEMPLE, a citi- 4zeri of the United States,residing at Wilming- "ticationu p In the statement of my invention inmachines for blowing glass articles the following description, read inconnection with the accompanying drawings, will enable any one skilledin the art to which my invention relates to understand its nature and topractice it in the form in which I prefer to employ it; but it will beunderstood that my invention is not limited to the precise form hereinillustrated and described, as various modifications and equivalentchanges may be made and adapted by the skilled constructor to carry outmy invention.

` My invention embodies certain novel parts and combinations of parts,which will be particularly pointed out in the claims concluding thisspecification, and I wish to state that in such particulars many of thedevices are not essential to the several features of my inventionseparately considered. This will he indicated in the claims, as in anygiven claim the omission of an element or the omission of reference tothe particular features of elements mentioned is intended to be a formaldeclaration of the fact that the omitted elements or features are notessential to the invention therein covered.

As shown, the machine is morganized for blowing bottles, but obviouslythe high-pressure-air device may be employed for blowing rotherglassware.

Referring to the drawings, Figure 1 represents the machine with itsrotating mold-carrying beam in side view, one of the molds, themechanismfor rotating it axially, and the blow-Valves at each end ofthenlold being shown in4 section in their normal closed positions, theTiller-wheel and gearing for' rotating the mold-carrying beam beingremoved. Fig. 2 is an enlarged sectional view of the mold and itsaxially-rotating and blowing connections, the coat-.ting valves forblowing by a sudden airbolt the neck of the bottle through the bottom ofthe mold being in their closed or inoperative relation to the mold andto the high air-pressure source and the plunger-valve in its openposition in the neck of the bottle, which is seen as having been blownand expanded within the mold, and it will be understood that in being soblown the mold will be swung over through a half-circle to an uprightposition on the table, as seen in elevation in Fig. l. Fig. 3 shows insection the mold, the coacting valves in operative or open positions todeliver suddenly into the mold air under high pressure to form the neck,which is seen as having been blown in the charge, and the plunger-valvein its closed relation to the neck of the mold and in position to formthe blow-hole in the charge preparatory to uncovering the blow-hole tothe air, such uncovering being effected. by the positive movement of theplunger-valve, as seen in Fig. 13. Fig. 4 is an end elevation of themachine looking from the right of Fig. 1, showing the rotatingmold-carrying beam in vertical position, one of the air-.compressorsremoved, and the independent eccentric-strap connections for the pistonsof both compress- 01's. Fig. 5 shows the treadle clutch-lever foreffecting the release of the mold from the beam to permit the removal ofthe blown bottle in a way I shall hereinafter describe. shows in sectionthe rotating mold-carrying beam, the air-compressors thereon, and theeccentric, and, by the rotation of the beam, the piston of onecompressor is seen at the limit of its air compressing and displacingstroke and the piston of the other compressor at the limit of itsair-suction stroke. Fig. '7 is a side view showing the tiller-Wheelandits gear connection with the shaft 2, on which the mold-beam is fixed.Fig. S shows the eccentric and its relation free of the shaft 2, takenon the line w00 of Fig. 6. Fig. 9 shows in top view thepivotally-mounted swing-tables which form a rest and a stop in theoperation of arresting the beam to remove the mold having the blownbottle and supporting the beam while blowing the neck of a bottle in theother mold. Fig. l0, Sheet l, shows the usual split-clamp ring used forthe split mold. Fig. 1l, Sheet 2, shows the plug-valve with its solidblow-hole-forming point; and

with which the plunger-valve coacts. Fig. 13 shows the neckbloW-holeuncovered; and Fig. 14 shows treadle, its stop, and spring forholding it in its normal position.

The frame in which the operating parts are mounted is preferably carriedon wheels to render the machineportable and is composed of sidestandards 1 1, connected at their upper and lower ends. About mediatelyof their height and in suitable bearings in the standards is mounted torotate a'horizontal shaft 2, which carries the operating parts. On thisshaft, about mediately of its length, is fixed a beam 3, mediately ofits length, and has suitable provision whereby the mold parts andblowing devices are mounted and operated at each'end of the beam. To thestandard at one side of the beam is fixed 'a master bevelgear 4, Fig. 4,so that the shaft and the beam must rotate together and independent ofthe master-gear. On the other side of thebeam an eccentric 5 is suitablyfixed on the other standard, so that the shaft passes through a slot 6in the eccentric; but the latter has no connection with the shaft, asseen in Figs. 6 and 8. Suitably'fitted to rotate on this fixed eccentricare two straps 7 7, Fig. 6, side by side, each pivotally connected by arod 8 to a piston 9. Mounted on the beam at its side,

at or near its end, is a trunk-cylinder 10, and

Within which the pistons are respectively fitted. The piston-rods are ofequal length, and their relation to the fixed eccentric is such that therotation of the beam will give equal strokes to the pistons by reason ofthe fixed relation of the eccentric to the shaft. This fixed relation ofthe eccentric and the shaft is such that the eccentric projection iscentrally in line with the piston-rods, which therefore are caused toreciprocate as their separate straps are rotated on the fixed eccentric.

Each cylinder has an air-outlet 11, which connects With the `mold,and anair-inlet valve 12, so thatthe beam, which carries a mold at each end,carries also an air-compressor at each end. 'lhe preferredarrangement isthat the molds shall be on the ends of the beam and the compressors atthe side thereof, so as to form a compact relation of the beam, its

molds, the compressors, and their operating eccentric. A convenientconstruction for mounting the molds on the ends of the beam andproviding effective means for imparting to them an axial rotation, whileat the same time they are rotated with the beam, is best seen in Fig. 2,wherein ball-bearings are provided for the axial rotation of the molds.At its ends the beam terminates in aring 13, the axis of which iscentral with the mold and which is preferably bolted to the fianged endof the beam, so that theaxis of the ring stands at right angles to theline of the beam, as in Fig. 1. At one of its open sides the ring has aninward-projecting rim or ange 14, upon which is fitted, in theangleagainst the inner wall of the ring, a concave ring-seat 15.v `At itsother open side the beam-ring has an in terior-Wall screw-thread toreceive a concave ring-seat 16, Fig. 2, the concave sides of thering-seats being opposite and c0ntigu'ous,and 7o each forms araceWay-bearing for a train of balls,upon which the base-section of themold is mounted to rotate. This base mold-section consists of acup-'shaped casting 17, having at one end an external `rim or flange 18,matching the internal rim 14, on which a ringv 19 is fitted against theouter Wall of the said cup and is formed with concave seats matchingthose of the beam-ring and completing' raceways for the ball-bearings onthe beama So ring and the cup. A ring-screw 20, engaging the wall of thecup, retains the double concave ring-seat 19 in place upon the flange 18and the ball-seating parts, and the cup presents a level face-supportand seating for a base split-clamp lock 21, whereby the mold is causedto rotate upon the beam-ring. The lower edge of the cup has a cog-gear22, and centrally within this cup is fitted a tubular plug 23, whichprojects beyond rthe cup and 9o forms a lock-seating for the mold andfor the clamp 2l. The other end of the cup has a ring-screw 24, which,engaging the outer projecting end ofthe cup,binds the tubular plug, byits circumferential shoulder 25, Fig. 12, upon an annular shoulder-seat25 on the inner wallof the cup, Fig. 2. At its mold-seating end thetubular plug has an oblique circumferential undercut 26,which forms anannular shoulder on a plane with the end of the roo cup to receive thesplit clamp 21, which has a corresponding oblique part engaging acircumferential undercut27, formed' at the base of the mold, whereby themold is clamped to and upon the flat end of the tubular plug,

Fig. 2.

Within the tubular plug is fitted a tubular stem 28, Fig. 11, whichforms a passage for air in blowing the bottle and is slidable to openand to close such air-passage, aplug- 11o valve v3l operating at themold-seating of the tubular stem for controlling the inlet of the airfor blowing the bottle and also forms the initial blow-hole in thecharge by a solid point 30.

The tubular plug has an annular cavity 29 in its mold-seating end, Fig.l2, and the moldchamberis contracted atits seatingeud,which forms acontinuation of the plug-cavity 29, Within which the neck of the bottleis blown. 12ov Within this cavity the tubular stern-valve terminates inthe solid point 30, having a length'suicient to pierce the neck formedon the charge andv form a hole therein about an inch, more or less, asin Fig. .8. The hole is 125 preferably made flaring to the mouth of thebottle, so that when the plunger air-tube is Withdrawn the hole will beuncovered around the solid point for the passage of the air from thetubular valve into the hole in theneck in 13a the operation of blowingthe bottle.

At the base of the point 30 the-stem 28 forms the valve 31, whichreciprocates in au annular seat-opening 32, Fig. 12, joining theneck-forming cavity 29 of the mold-seating plug, so that when thestem-point is projected into the neck of the charge, as in Fig. 3, thevalve will close the cavity 29 at the mouth of `the neck, and therebycut off the air-passage thereto while the neck and the blow-hole arebeing formed in the charge. The valve-seat 32 opens into an enlargedpart 33 of the plug, into which opens the air-passage 34 of the stem,which communicates with the air-com pressor and with the mold by theside holes 34",Figs. 1l and 13. The plunger-valve stem is open at itslower end and projects a sufficient distance beyond the base-cup '23 forconnection with the air-compressor and with a lever 35, by which the plunger-valve is actuated. The stem of the plunger-valve tits closely thewalls of the bore of the cup 23, but is free to slide therein, and itsouter end terminates in a collar by which it is clamped within andbetween the screw-couplings 39 41, and itis the coupling part 39 whichforms the connection for the lever which reciprocates the plunger- Valvewhich rotates with the mold, the friction of the valve-stem in the boreof the tubular plug 23 and stuffing-box being suficient to cause suchrotation or to allow the i tubular cup and the mold to be rotatedindependently of the air-tube.

The extent of the movement of the plugvalve is limited by the vibrationof the lever caused by the deflection in the cam-groove, and as eachmold has identical lever connections the cam-groove actuates both leversas the beam is rotated to cause the valve of one mold to be closed andthe valve of the other mold to be opened while the molds are standingasin Fig. 1.

The air-compressor connection is made by a rubber tube 36, and in orderthat such connection will permit of the rotation of the plunger-valve 28with the mold the rubbertube connection with the stem of theplungervalvelis made by a ball-and-socket joint. As seen in Figs. l, 2,and ll, this j'oint connection is made by the-ball-stem 37, fastened tothe rubber tube and inclosed in a couplingnut 38, which is screwed on ascrew-section 39, which has a concave seat 40 and is coupled to theplunger-valve by a screw-ring 4l, mak ing a seat-joining. 'lhe`coupling-nut 38 is hollow and is adjustable to give more or lesspressure upon the ball-stem. A stuffing-box 42 seals the plunger-valvestem 28 with the base supporting-plug 23, so that the rubber tube allowsthe plunger-stem to have a longitndinal movement to open and close itsvalve and for a limited projection into the neck of the mold and arotary motion with the mold. A spring 43 maintains the sealed contact ofthe ball-and-socket joint, said spring being seated in the coupling-nutand against the ball-stem 37 for pressing the latter against thevalve-stem 34 by the coupling 39.

Referring to Figs. 2, ll, and l2, it must be understood that the tubularvalve-stem 28,

the tubular plug 23, and the mold are the parts which are rotatedtogether upon the ball-bearings, because they are clamped together uponthe seating-gear cup by the shoulder 25 and the ring-nut 24, while thetubular stem 37 forms the non-rotating part which connects with theair-compressor and affords a free bearin gj oint and a free passage forthe air in blowing the article. It is important to note that theair-tube,with its blowhole-forming plug, does notindependently rotate,neither does the article being blown independently rotate, because itsneck .having been first blown into the cavity of the tubular plug andinto the neck forming part of the mold which is seated upon and is fixedthereto, and they are therefore rotatable together as an entirety andcarry the article being blown with them. This construction allows theblow-hole-t'orming plug 30 of the air-tube to remain within and rotatewith the ball of glass and the mold until the latter has started uponits swing movement, after which the air-tube is withdrawn so as touncover the blow-hole.

The means for opening and closing the plunger-valve is a cam-groove 44in the side of the iixed master-gear 4 and a lever 35, pivoted to theend of the mold-bearing beam and engaging the outer end of theplunger-valve by a suitable coupling. This lever travels in the groove44 with the rotation of the beam, so that a deflection 45 in the grooveacts to vibrate the lever, and thereby force the plunger inward andoutward to project its solid inner point into and out of the neck of themold for the two purposes of cutting off the air and forming the initialblow-hole in the lump of glass as a preparatory step in blowing thebottle, Figs. 3 to 13. For this purpose the lever has a clutchconnection 39 with the plunger-valve, whereby it is free to rotate withthe mold.

The neck of the bottle is blown by an airbolt projected through thebottom of the mold, which during such operation stands inverted, and theprovision for effecting this blowing consists of a pivoted swing-valveddevice which is in communication with air under high compression and ismanipulated by the attendant. This valved device, as shown, consists otan arm 46, mounted to swing horizontally on a rod 47, secured to thestandard, and a spring-sustained arm 48, plivoted to the end of theswing-arm, so as to have a vertical movement on said pivot, and having avalve and an independent air-supply connection therefor. This pivotedarm has a tube 49, standing transversely open at both ends, and atubularvalve 50 seated therein, adapted to close the upper end of the tube 49,which has communication with the storage-tank 84 above the valve. Thistubular Valve 50 terminates at its lower end in a conical formation 5land is adapted to be opened by contact-pressure applied to its conicalend when seated as a stopper in the open end Iof the IOO IIO

tubular mold-cap 55, so as to lift the closed end 52 of the tubularvalve from its seat. This opening movement of the valve is slight and islimited by a shoulder 53, abutting against the lower end of the arm-tube49, which permits the arm 48 to be held down under slight pressure toseal its communication with the mold-tube when applied thereto. For thispurpose the mold is provided with a stem-valve 54, fitted in a tubularbase 55, which is seated and clamped upon the bottom of the mold, so asto open centrally into the mold, and within the outer open end of whichtubular base the tubular conical end 5l of the air-inlet Valve 50 iscaused to enter to effect communication of the air-storage tank 84 withthe mold, as in Fig. 3. This mold-valve 54 closes the bottom of the moldtubular base by a spring 56, the tension of which need only besufficient to keep the valve normally closedand is opened by thepressure of an incoming air-bolt on a perforated bntton 57, fitting thetube on the outer end of the valve-stem. This tubular base 55 is clampedupon the mold by a split ring 58, like that shown in Fig. 10, while themeeting faces of the tubular base 55 and of the mold are such as tointerlock them with a sealed joint, which secures the base against theinternal air-pressure in blowing the bottle, as in Fig. 2.

The connection of the swing-arm valve 50 with the air-storage tank 84 ismade byia rubber tube 59, connected to a branch 59 of the tubularseating 49 for the valve 50, so that the arm 46 can be swunghorizontally into position to be joined with the mold-valve and thendepressed vertically to effect such junction by the open end of theValve 50 making contact with the mold-tube 55.

The valve-carrying arm is held normally horizontal by a spring 60 on theswing-arm 46 engaging an extension 48' of the pivoted arm 48 between thesaid pivot and the mounting-rod 47 of the swing-arm, so that the arm 48is depressed against the tension of the spring and raised when releasedfrom pressure by said spring.

To limit the downward-pressing action of the spring upon thevalve-carrying arm 48 and to hold it in position to instantly set itsnozzle or stopper end 5l upon and in communication with the open end ofthe mold tubular cap 55, the inner end of the swing-.arm is pressed bythe spring 60 upon a lug 77, iixed on the swing-arm 46, as in Fig. l.

To properly set the arm 46 so that its horizontal swing will carrythevalve-arm 48 above and clear the open end of the tubular cap, theswing-arm is provided with a split clamp 78, by which it may be sethigher or lower on the vertical stem 47 to suit different sizes of molds79. By this construction the limitingpof the downward swing of the moldin which the article is being blown will limit the upward swing of theother mold in its relation to the Valved swing-arm. Whatever, therefore,the

length of the mold, the tableand the swingarm can be relatively set tosuit such length to render it easy to place the pivoted valved arm incommunication with the mold tubular cap.

The high-pressure valve is fitted closely in the tubular seat, with itsupper end forming a solid valve-head 52, closing the seat. Thevalve-seat opens into a chamber 90, closed by thescrewcap,which connectsthe iiexible tube 59 with the storage air-tank,so that air therein underfull pressure is in constant communication with the valve-chamber andkeeps the Valve closed by such pressure. The communication of thischamber 90 withithe Itubular passage of the valve is by holes l91 at thejunction of the valve-head with the tubular stem, and the valve isopened by lifting it against the pressure of the air in thestorage-tank, v

and when' so lifted uncovers the wall-holes 'and the air from thevalve-chamber passes into and through the tubular valvefthereby opensthe mold-valve and is projected upon and drives the charge intothedesired shape. The provision for this high air-pressure--say aboutiive hundred pounds-not only gives greater volu me, but much greaterforce than the provision for blowing the article through theplunger-valve. Therefore the degree of air-compression in the piston-compressors is less than that in the storage-tank and is agradually-increasing air-pressure, but must not have undue forceto blowthe charge into too-thin walls. Moreover, the control of the air in boththese blowing operations renders it only necessary to charge the mold todepress the high-pressure-air device to form a j nnction with themold-valve and to finish the article while on its Way to the point forremoval.r

It is important to note that the mounting for the swing-arm 46 and themounting of the mold must be such that the swing movement of the moldwill bringit to a point of rest, with its axis in vertical alinementwith the axis of the high-pressure tubular air-valved connection, andthat the fulcrum of the valved lever-arm must be so located as toallowits tubular valved part to be depressed in a line coincident withthe axial lineof the mold.

Convenient means for effecting the rotation of the shaft consists of atiller-wheel 61,mount *ed on one of the standards carrying a pinion 62,which engages a gear 63 on the end of the saidshaft, whereby themold-carrying beam is rotated intermittently through an arc of half arevolution, at which position it is stopped and seated toallow one ofthe molds to be filled and the other to be removed for .the removal ofthe blown bottle and the replacement of the mold in the continuousoperation ,of the machine, as I shall more particularly hereinafterstate.

The rotation of themold-carrying beam is' utilized as means foreffecting the rotation of the mold on its axis while the bottle is beingblow-n, and ,for this purpose the master-gear 4 is loosely mounted onthe shaft adjacent to IOO IIO

tilt

the mol d-earrying beam and fixed to the frame so thai it cannot turn bya bracket da, fastened tothe `gear and to the standard, as in Fig. 4.Engaging this master-gear is a pinion 65 on the end of a short shaft6,6, mounted in the end of the beam, so as to stand radially with themain shaft, and has a bevel-pinion 67, which engages the bevel-gear Z2on the end ofthe mold-supporting cup, whereby in rotating themold-carrying beam the pinion carried byit is caused to roll over thefixed master bevel-gear and be rotated thereby to cause the rotation ofthe mold during the half-revolution through which its carrying-beam isswung, so th-at the starting of the swing movement thereby starts theaxial rotation of the mold.

I have stated that the mold-carrying beam has anintermittent rotarymotion in the operation of blowing and delivering a blown bottle, andreferring to Fig. 1 it will be seen that the mold at one end of the beamis in its rotation arrested by a table standing horizon- -standards, sothat when closed their meeting faces join, Fig. 9, and form a stop tothe rotation of the beam and a table on which to support the tubularvalved base 55 when unclamped and the mold 19 freed thereby to beseparated for removal therefrom to open it to remove the bottle. Theseshelf parts are made adjustable by nuts on the screwthreadedbearing-stems 69 to allow different lengths of molds to be worked fordifferentsized bottles.

The swing-arm that carries the high-pressure air-valve can be raised orlowered to accommodate ditereut lengths of molds, and as the rotatinglbeam travels the same distance at all times the handles of the moldswill stand in the same place infront of the attendant at the table.

'2 Referringto Fig. 1, the beam has been swung to carry one of the moldsto the table for the removal of the blown article and the other mold inposition to receive the charge. To remove the mold, with its blownarticle, the split clamp 21 must be opened by its handles 8O to releaseits locking connection with the neck-forming plug 23 and with theneck-forming part ofthe mold. The split clamp 58 is also opened by itshandles 8O to release the mold from the tubular base 55, which thenrests upon the table. While thus unlocking the mold the beam is helddown tight on the mold by the attendant pressing upon the treadle, whichacts to lock the shaft by means or' the ball and ratchet-clutchconnections 72 73, as seen in full lines in Fig. 14. The attendant thenreleasesthe treadle, and this end `of the beam being freed from the moldwill rise by reason of the weight of the mold being charged, carryingthe plug 23 away from the `neck ofthe bottle, so that. the mold can be`table parts.

effecting such limit, as seen by dotted lines in' Fig. la. The moldhaving been replaced upon and locked to the tubular base part 55, theattendant again depresses the treadle, lturning the shaft forward tobring the beam-plug 23 down upon the mold, which having been locked tothe beam-plug the treadle is released and is normally held out ofengagement, in the position shown by dotted lines in Fig. 14, with theshaft-clutch by the spring 90, attached to the standard and bearing uponthe treadlearm, forcing it in its normal position against the stop. Thetables are then opened and the beam rotated to carry the replaced moldto the position to be charged in the continuous operation of themachine.

In the action of the clutch it will be linderstood that the treadlehangs loose upon the beam-shaft, allowing the latter to rotate freelyforward, that the ratchet 73 is fixed on the shaft, and that the balls72 are caused to engage the ratchet-teeth and the treadle-sleeve hubwhen the treadle is pressed down to turn its clutch-sleeve hub in thedirection of the arrow, Fig. 5. In arresting the intermittent swingingrotation of the mold on the table the axial rotation of said mold isthereby stopped and the tubular neck part of the valved base passesthrough the hole 83, Fig. 9, formed for it between the meeting edges ofthe swing- The treadle in its holding function on the beam to allow themold to be removed therefrom also serves to support the mold at theother end of the beam against the downward pressure of the high-pressureair-lever device upon the mold. It will also be noted that the molds arearranged t'o stand in opposite directions and substantially at rightangles to the beam, so that when one mold is in inverted position toreceive the charge the other mold will stand upright at the other end ofthe beam in position to be opened for the removal of the blown bottle.This arrangement is advantageous as alording a balance to the beam, aseach end has identical construction of mold and air-compressorconnections and identical gear connections with a central fixedmastergear, whereby each mold is caused to be rotated on its axis.

In operation the mold-carrying beam is stopped and maintained in ahorizontal position for charging one of its molds and removingfromitsother mold the blown bottle, and, referring to Fig. 1, it will be seenthat the mold heilig charged is in an inverted position, while the othermold has been carried over to its table-support on the other side of themachine, withits neck-forming part stand- IOO IOS

ITO

ing up. In this position the tubular valved bottom part 55 of4 theinverted mold is removed and a charge ot' molten glass from a puntydropped into the open mold upon the solid point 3Qof the plunger-valve28, as shown in dotted lines, and the tubular valved part replaced andlocked. This position of the beam brings its cam-groove'd actuated lever35 in the defiected part 45 of the groove 44 so as to lift and hold theplunger-valve with its solid point at the limit of its inward movementinto th plug 23, closing it at the end ofthe neck-forming cavity,whichgives sufficient space around the plunger-point to form the bottle-neck.The high-air-pressure valved lever 48 is then swung over the mold andpressed down, bringing its nozzle 5l under pressure close-l y seatedas'a stopper upon the upper open end of the tubular base valved part 55,which pressure causes the lever-.valve 50 to be lifted, thereby openingcommunication with the high-pressure air-supply or storage-tank 84, theairbolt from which instantly depresses and opens the stem-valve 54 andallows the air to be projected with a blow into the mold, striking anddriving the molten glass down over the point '30 of the plunger-valve,so as to form in the glass an initial blow-hole, at the same timeforming the neck of the bottle, as in Figs. 3 to 13. This is but amoments work, and the valve-lever is then swung to one side and thetiller-wheel rotated, carrying the mold over and seating it upon thetable. This half-circle swing brings the empty mold to the position fromwhich the charged mold'started, while at the starting of this swingmovement the plunger-valve 28 is withdrawn by the action of thecam-groove 45 upon the. lever 35. which connects the stem of said valve,and thereby opens the passage to the mold for the entrance of air intothe initial blow-hole. Itis during this half-circle swing of` the moldthat the bottle is blown, and the air for this purpose is furnished bythe air-compressor, the piston of which is caused by the action of thefixed eccentric to be forced inward, driving the air out under agradually-increased pressure through the rubber tube 36, through theplunger-valvminto the blow-hole of the charge of the glass,expandingwand forming the bottle around the walls of the mold,"as inFig. 2. The xed eccentric, while thus forcing the piston into thecompressor as the mold is traveling through the half-circle, is at thesame time and to the same extent withdrawing the other piston from theother compressor, so that when one mold reaches the position to receivethe glass charge the piston of its air-compressor is at the limit of itsoutward stroke drawing in air, and the piston of the other compressor isat the limit of its inward stroke, having forced out the air, the bottleis blown, and the mold seated upon the table to be removed from thebeam. In this way the operation is made continuous, the mold-carryingbeam being rotated vertically and the fixed eccentric causing thealevavie ternate projection and retraction of the pistons at eachrevolution of said beam. This relation of the pistons and their relationto the fixed eccentric is seen in Fig. 6, the projection of ,theeccentric to one side of its shaft being in theline ot' the piston-rods,and therefore both pistons are at the limit of their strokes when thebeam stands horizontal. In this i'gure is seen how the fixed eccentrichas forced the independent strap of each pistonrod to project one pistonand retract the other, and this result is obtained by having independentpiston connections on one and the same eccentric.

It is important to regulate the pressure of air forced from thecompressor to suit different sizes of bottles, and for this purpose Imake provision for adjusting the eccentric upon the standard, so as toincrease or diminish the extent of the projection of the eccentric atone side of the shaft. To allow for this adjustment of the eccentric, itis secured to the standard bv a bracket 74, as seen in Figs. 4 and 6,and the adjustment is made by nutted bolts 75, which pass through armsin the bracket and through slots 76, standing horizontal in theeccentric on each side of the shaft, as in Fig. 8. The eccentric alsohas a horizontal slot 6, which permits it to be set over the shaft 2,which passes through it, and the eccentric is therefore independent ofthe shaft. In setting the eccentric for this purpose it is onlynecessary to loosen the bolts 75 and move the eccentric thereon toeither side of the shaft to give the eccentric more or less projectionon one side thereof. The greater this projection the longer will be thestrokes of thepistons and necessarily an increased .pressure of air willbe forced from the compressors, and vice versa.

In the blowing operation it is necessary that the mold should be rotatedon its axis to give uniform thickness to the walls of the bottle whilethe mold is being swung upwardand over and down to its seating on thetable. In these two movements of the mold the blowing is first in anupward direction into the neck of the bottle and terminates in adownward direction, and it is these two axial and swing movementscoacting that gives a'uni-l form thickness to the walls of the bottle bycounteracting the tendency of the glass to gather on one side of themold from the force of the swing movement. This swing movement, it willbe observed, is rendered comparatively slow by theprovision of thetillerwheel and its pinion engaging a larger gear on the shaft, whichrotates and carries the moldcarrying beam, while the rotation of themold on its axis is rapid, because the master gearwheel drives the smallbevel-wheels 65 and 67, the latter of which engages with the gear 22 ofthe cup on which the mold is clamped and which is supported by theball-bearings. As the intermittent swinging rotation of the pair ofmolds is to render the operation continuous in blowing the article inone'mold IOO IIO

- of the mold automatically sets in motion its axial rotation,whi1e thearrest of the swinging movement of the mold automatically causes thestopping of its axial rotation, the swing movement being comparativelyslow to allow the glass to shape itself aroundthe Walls of the mold. Themold operated in this way causes the article to be blown at one and thesame operation, in which three forces coact continuously--that is, ablowing force under a gradually-increasing pressure, a centrifugal forcedue to the axial rotation of the mold, and a swinging movementthereof-each force having a separate and distinct function in thecompletion of the article. The result of the gradually-increasingpressure of the air is to cause it to have a uniform force in expandingthe glass as the latter is caused to iill the mold. In my process theembodiment in an operation of one step of three forces acting as a unitis the conning of air injected under a gradually-increasing pressureinto a charge of molten glass, while at the same time the charge issubjected to two continuous simultaneous movements, whereby the air iscaused to be directed and to have a central action within the charge,whereby that side of the glass Wall which stands toward the direction ofthe swing movement will be prevented from be- `ing blown into a thinwall or away to nothing. The holding of the air central in the ball ofglass is the important function of the operation of blowing, rotating,and swinging the mold, and in the art of blowing glass I believe myselfto be the first to employ these three forces in their coperatingfunctions. I have stated'that the article is blown under agradually-increasing `airpressure, and I mean by this that the capacityof the aircompressor is irst determined, according to the size of thebottle to be blown', to give the proper volume of air for blowing it,and the treating this limited volume of air by compressing it with agradually-increasing pressure,so that as the pressu re increases theglass expands to take it up, the volume of air being therebyneitherincreased or diminished. At the moment of the commencement of theoverswing ot' the mold the piston of its air-compressor commences toforce air into the mold to blowand expand the glass around its walls,and the ail-pressure is gradually increased to cause the glass to beuniformly expanded against the walls of the rotating mold until the moldis seated upon the table, meanwhile the piston returning by the underswing is being retracted, drawing in air till it reaches the point fromwhich the other mold started, and is therefore ready for its blowingfunction in starting the mold in its overswing movement. In this way therotation of the mold-carrying beam is controlled by hand by turning thetiller-wheel, which at the same time and by the same movement controlsthe movements of the air-compressing pistons.

It is important also to not-e that the air-compressor is in perpetualcommunication with the tubular plunger-valve and that such communicationwith the mold is controlled by the plunger-valve at the point where theneck of the bottle is formed.

It is also important to note that the operation of blowing the bottle iscommenced while the mold is in an inverted position and is tinishedduring a movement in which the mold is swung over through an arc of halfa circle, while the empty mold is by the same swing brought to theposition to receive a charge of glass to repeat the operation.

It is only necessary to give the tiller-wheel a few turns to eifect theblowing of the bottle during the swing of the mold through halt' arevolution, and the mold is delivered with its blown bottle with an easystop upon a table.

The sectional mold, its clamps, and the pivoted table-forming parts areeach provided with handles, by which they are opened and closed, as seenin Fig. l.

In forming the blow-hole in the charge the importance of such hole liesin being uncovered after being formed for the purpose of freelyadmitting the air therein independent of the plug-valve, which iswithdrawn to uncover the neck and hole for this purpose. Thisconstruction permits the point of the plunger-valve to be made solidinstead of being perforated, as hitherto used, and in which use theblow-hole cannot be uncovered as an initial step in the blowing andexpansion of the glass.

The air-storage tank 84 may be conveniently placed near the swing-armand kept under high pressure from a pump (not shown) by a suitablevalved connection 85.

While it is important that the valve which controls the high pressureair should be opened suddenly to admit air in large volume and underhigh force to drive the molten glass solidly into the form of the mold,it is equally important that the valve which controls the blowing of thehollow article should be opened and closed slowly to gradually admit andcut oif the air, because high-air force under sudden projection is notsuited to blowing glass into thin walls. For this reason the ends of thedeiiected part of the cam-groove are inclined to give a gradualvibration to the lever 35 in passing from the part of the groove whichholds the valve closed into the part of the groove which holds the valveopen, as seen in Fig. 1. In this way the rotation of the beam causes theplunger-valve of the mold moving to the position to receive the chargeto be IOO ITO

' opened and the plunger-valve of the other mold to be opened to effectthe blowing of the article while the mold is under a compound movementof being rotated on its axis and swung to the position at which the moldis removed for the removal of the blown article.

Referring to the separate and distinct airpressures, and particularly tothe importance of providing different pressures for the two separateblowing operations, it will be seen nected arm. The air then enters theblowhole in the formed neck at a very low pressure, because theeccentric will then be working oif the dead-center part. As the beamprogresses in its swin g the eccentric increases the speed of theair-compressing piston, and i therefore increases the pressure for theblowing.,v The action of the eccentric is such that the air for blowingis gradually increased in pressure, because if the air were let into themold from a tank of uniform high pressure the glass would be splatteredor pued out in a blister and the centrifugal action on the glass due tothe axial rotation of the mold would be without effect.
